Resistor watt rating for R27?

Postby mikew » Sat Sep 19, 2009 6:31 am

Hello,

Curious if someone could help me determine the watt rating I need to get for the resistor across R27?

Thanks as always,

- Mike

i have a related question -- after putting all resistors in except r27 and r28(which i don't plan to use) i am left with three beige resistors with a black stripe in the middle -- i believe these are 0. does this turn the trim knob into a full fader ? is there actually any advantage to havine a full fader on this style of preamp as there is nothing to really "drive" in the circuit ?

R27 calls for a 0r0 which these three appear to be -- but i am only supposed to have received 1. did i just accidentally receive 2 more and 1 0r0 goes in r27 -- or are these three used elsewhere (non resistor slots) and i am just missing the 10k for r27 ?


sorry for the rambly post -- this is my first real DIY project and i want to be exact.


thanks for a great kit!

1/4W metal film, same as the rest.

If you're not sure about the value of a resistor, measure it. They are indeed zero-ohm jumpers. You must install something at R27 or R26 will have little to no effect. Use one of the zero ohm jumpers here. Use the other two jumpers at L3 and L4 if you're not installing the optional load isolators.
